D for me.

According to the argument, xylophones Cost Price = 30 % of total manufacturing cost.
xylophones revenue = 40 % of total revenues.

Nothing concrete is mentioned about any other product. Hence the choice should be the one that deals only with xylophones.

what a question sirji !

+1 D

as crick mentioned, logically only D stands a chance to be the contender, and by POE too only D remains. Kudos to both of you.

I verified it mathematically and here it is:

Total Cost Incurred = X
Total Revenue = Y
Total Profit = Y - X
As given in question, the company has operated profitably,
=> Profit is positive
=> Y - X > 0
=> Y > X
=> 1 > X/Y
=> -1< -X/Y .... (1)

Now, we are also given,
Costs Incurred on Xylophone = 0.3X
Revenues from Xylophone = 0.4Y
Profit on Xylophone = Revenues - Costs Incurred = 0.4Y - 0.3X .... (2)

Profit margin = Profit/Revenue

=> Profit Margin for Xylophones = (0.4Y - 0.3X) / 0.4Y
= 1 - 0.75(X/Y)

Using (1), we have:

Profit margin on xylophones = 1 - 0.75(X/Y) > 1 - 0.75 = 0.25

=> Profit Margin is greater than 25%

+1 for D.

A), b), C) are all wrong because you don't know what the cost of W, Y, and Z is individually. E is wrong because you don't know what the revenue was in the n-4 year.

Rev = 150 X = 40/100 * 150 = 60

Cost = 100 X = 30

thus profit % = 60/30 * 100 = 200

thus D is clearer than B.

More so,B uses 'most' which is a red flag.

D it is.

I will go with D , as all other options can be neglected because :

A.From original question stem widgets, yo-yos and zippers all constitute 60% and it is no mentioned which carries how much waitage .
B.Says Xylophones are the most profitable, which is not clear as the revenu share of the other three products is not given.
C.Irrelivent as neither cost price nor revenue share is given
E.Not mentioned in the question stem
D> That leaves D

I verified it mathematically and here it is:

Total Cost Incurred = X
Total Revenue = Y
Total Profit = Y - X
As given in question, the company has operated profitably,
=> Profit is positive
=> Y - X > 0
=> Y > X
=> 1 > X/Y
=> -1< -X/Y .... (1)

Now, we are also given,
Costs Incurred on Xylophone = 0.3X
Revenues from Xylophone = 0.4Y
Profit on Xylophone = Revenues - Costs Incurred = 0.4Y - 0.3X .... (2)

Profit margin = Profit/Revenue

=> Profit Margin for Xylophones = (0.4Y - 0.3X) / 0.4Y
= 1 - 0.75(X/Y)

Using (1), we have:

Profit margin on xylophones = 1 - 0.75(X/Y) > 1 - 0.75 = 0.25

=> Profit Margin is greater than 25%

Great explanation.

(D) is the answer. Costs_Xylophone=30% of total cost. Revenue_xylophone=40% of total revenue. Total cost<Total revenue (since company operating profitably). If total cost = total revenue, profit margin of xylophones=25%. Thus, profit margin of xylophones>25%.
(B) is the red herring. Who knows what is the exact breakup of costs and revenues in the grouping of widgets, yo-yos and zippers. For eg., yo-yos can contribute 15% of total revenues and only lead to 10% of total costs. This implies a minimum profit margin of 33.33% (greater than xylophones)...

Not a 700 level question.

Choice D is the correct answer. With this type of question. The quickest way is to guess. :D
